Hello Anjali,

There are a few chapters in Physics that have a greater weight age compared to other chapters.

Kinematics, Laws of Motion, Rotation, Electrostatics, Current Electricity & Capacitors, Magnetic Effects of Current & Magnetism, Electromagnetic Induction and Alternating Current, Waves and Sound,Bohr's Atomic Model.These chapters require high effort but they also has high weight age.Similarly chapters like Gravitation, Wave optics, Ray Optics, Heat & Thermodynamics, Photoelectric Effect, Semiconductors, Oscillations, Electromagnetic Waves have high weight age but they are comparatively easy to study.
